Abstract: In the recovery process of the reusable rocket with vertical take-off and landing, it has to go through the active control process, such as power drop, hover and vertical landing. The key technology lies in the development of high-precision vertical recovery control algorithm. Therefore, a vertical take-off and landing reusable launch vehicle prototype is developed to verify the rationality of the flight control algorithm of rocket vertical recovery.
The vertical take-off and landing reusable launch vehicle prototype is 0.45 m long, 0.45 m wide, 0.6 m high, and has 23 kg take-off weight with a maximum thrust of 400 N jet engine as the power plant, through four gas rudders to achieve the aircraft pitch and yaw and roll-on control. The prototype focuses on the verification of the guidance and control algorithm of the vertical recovery algorithm. Therefore, it is equipped with the vector control capability, avionics and measurement system similar to that of the vertical recovery rocket. The prototype can be used for verification of the flight control algorithm.
